Your air conditioning unit will always make some noise when running, and older units are louder than newer ones. Consider the age of your unit before getting too concerned about the noise that it’s making. At Eller Services, we recommend a maintenance inspection at least once a year to inspect the health of your air conditioner.
If the noise your air conditioner is making is unusual or is different from its regular hum there are a few things to consider.
How would you describe the unusual noise that your unit is making?
This could be from something that fell into the vents, or something that is loose. It could also be your compressor rattling. If it’s your compressor or anything more serious than a loose bolt, you will need a technician to look into the problem further.
Most likely this is one of the fan motors, or it is possible that there is a worn bearing.
This noise might be coming from your duct work when your AC unit turns off and on. This usually indicates a problem with your duct work and not with your central air.
Unless this noise is coming from your duct work, this could possibly be a refrigerant leak. If that is the case, you will need one of our technicians to handle the problem.
Your air conditioner is a piece of machinery with many moving parts and, like a car, it requires regular maintenance. Call us at 248-652-6650 or request service online!
